I'd like to know the same. Meps website shows the orange/green for USP which are different mount type (I think).
I have TFX Pros on my Kimber compact and love them. I was thinking of purchasing a P2000SK and putting TFX Pro sights on it.I just installed the TFX Pro's on my VP9 last month ($117 on Amazon Prime, used my friend's sight tool)... I absolutely love them! I still have the Meps on my VP40 LE, but will change them one day. The Trijicon HDs are also awesome sights.
